Description

Technical Field

[0001] This invention belongs to the field of soilless cultivation, specifically a smart vegetable cultivation device for home balconies. Background Technology

[0002] With the acceleration of urbanization and the increasing demand for healthy food, home balcony gardening is becoming increasingly popular. Existing home balcony vegetable growing systems are mainly divided into two types: soil cultivation and hydroponics.

[0003] Patent CN117859635B discloses a hydroponically grown vegetable device, including a base; a shell is connected to the top of the base, and two glass plates are connected to the shell, arranged symmetrically. A collection box is slidably connected to the lower part of the shell, and the collection box is in communication with the shell. When the operator starts a servo motor and a water pump, the water pump draws the cultivation water inside the shell to flow or drip into the shell, allowing the vegetables to receive more sunlight and also oxygenating the cultivation water inside the shell, increasing the oxygen content of the water, thus promoting vegetable growth.

[0004] The aforementioned patent allows vegetables to receive ample sunlight during cultivation and also oxygenates the growing water, which is more conducive to vegetable growth. However, relying solely on sunlight can lead to shorter periods of sunlight exposure for vegetables, especially in rooms with poor lighting or during prolonged periods of overcast or rainy weather. This results in shorter photosynthetic time for the vegetables, significantly reducing their ability to receive sunlight, thus prolonging their growth cycle and potentially causing a decrease in yield.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Active supplemental lighting is achieved through multi-layer LED plant growth lights, reducing dependence on natural sunlight and ensuring the duration and intensity of vegetable photosynthesis. The device has multiple LED plant growth lights installed at the bottom of each cultivation layer, and the daily operating time can be automatically set through the control component. When the balcony has poor lighting or long rainy days, these LED lights can actively provide a stable and adjustable artificial light source for the lower vegetables without relying on natural sunlight.

[0023] 2. This device achieves precise drip irrigation and automatic circulation oxygenation of nutrient solution, combined with stable light, to create a synergistic growth-promoting effect, further enhancing the growth efficiency of vegetables in low-light environments. The device uses a circulating water pump, main supply pipeline, and drip irrigation pipe to precisely drip nutrient solution into the roots of vegetables in each planting hole. Simultaneously, a return pipeline and recycling box achieve closed-loop circulation of the nutrient solution, effectively increasing the dissolved oxygen content during circulation. With stable light provided by LED plant growth lights, this precise oxygen and nutrient supply mode ensures that vegetable roots can still efficiently absorb water and nutrients even in low light conditions, maintaining vigorous metabolic activity. The synergistic work of the light and nutrient solution circulation system compensates for the shortcomings of simple light compensation, comprehensively optimizing the vegetable growth environment from four dimensions: light, water, air, and fertilizer, thus enabling rapid and healthy growth even in poorly lit environments.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 8As shown, the present invention provides an intelligent vegetable cultivation device for home balconies, including a three-dimensional support 100, a nutrient solution circulation component 200, an automatic solution replacement component 300, a control component 400, multiple LED plant growth lights 500, and a multi-layer cultivation layer 600.

[0043] The multi-layer culture layer 600 can be detachably connected to the inside of the three-dimensional support 100;

[0044] Multiple LED plant growth lights 500 are detachably connected to the bottom of the multi-layer cultivation layer 600;

[0045] The control component 400 is detachably connected to the side wall of the three-dimensional support 100;

[0046] The automatic fluid changing assembly 300 is detachably connected to the bottom of the three-dimensional support 100;

[0047] The input and output ends of the nutrient solution circulation component 200 are both inserted into the inner cavity of the automatic liquid replacement component 300;

[0048] A conduit is provided between the multi-layer culture layers 600 and at the bottom of the culture layer 600, and the conduit is inserted into the nutrient solution circulation component 200;

[0049] It should be noted that the three-dimensional support frame 100 provides structural support for the entire device, and the multi-layered cultivation layers 600 are vertically distributed for layered vegetable planting. LED plant growth lights 500 are installed at the bottom of each cultivation layer 600 to provide light for the vegetables in the next layer. The control component 400 collects nutrient solution status signals and controls the operation of the automatic nutrient solution replacement component 300 and the nutrient solution circulation component 200. The nutrient solution circulates between each cultivation layer 600 and the automatic nutrient solution replacement component 300 through conduits, thereby making full use of the vertical space of the balcony, increasing the vegetable yield per unit area through layered planting, and providing a structural foundation for subsequent automatic circulation and nutrient solution replacement.

[0050] like Figure 3 as well as Figure 4 As shown, each of the multi-layer culture layers 600 includes a support plate 601 and a planting plate 602. The multiple support plates 601 are arranged in a vertical linear array. Multiple culture grooves 603 are opened on the upper surface of each support plate 601. The planting plate 602 is detachably connected to the upper surface of the support plate 601. Multiple planting holes 604 are opened in the planting plate 602. The multiple planting holes 604 correspond one-to-one with the multiple culture grooves 603.

[0051] It should be noted that the cultivation trough 603 above each support plate 601 is used to contain nutrient solution. The planting plate 602 covers the cultivation trough 603, and the planting holes 604 are used to place the planting basket and hydroponic vegetables. The vegetable roots extend through the planting holes 604 into the nutrient solution in the cultivation trough 603 to absorb water and nutrients, thereby fixing the vegetable plants and keeping them upright. At the same time, it effectively contacts the plant roots with the nutrient solution, facilitating nutrient absorption. In addition, the planting plate 602 is removable for easy cleaning and replacement.

[0052] like Figure 3 , Figure 4 as well as Figure 5 As shown, an installation assembly 700 is detachably connected between two adjacent support plates 601. The installation assembly 700 includes a threaded sleeve 701, a threaded rod 702, and a drive assembly 703. The threaded sleeve 701 penetrates the support plate 601, and the threaded rod 702 is threadedly connected to the inner cavity of the threaded sleeve 701. The threaded rod 702 is fixedly connected to the threaded sleeve 701 that penetrates the support plate 601 of the upper layer. The drive assembly 703 penetrates the side wall of the support plate 601, and the drive assembly 703 meshes with multiple threaded sleeves 701.

[0053] It should be noted that the drive component 703 drives the threaded sleeve 701 to rotate, and the threaded sleeve 701 rotates relative to the threaded rod 702, thereby realizing the relative lifting or locking of the bearing plates 601, which facilitates disassembly and adjustment of the layer height, and realizes the quick disassembly and assembly and height adjustment of the cultivation layers 600. This allows users to flexibly adjust the layer spacing according to the growth height of different vegetables, and improves the adaptability of the device to different varieties of vegetables.

[0054] like Figure 4 as well as Figure 5 As shown, the drive assembly 703 includes a worm 7032 and a plurality of worm wheels 7031. The plurality of worm wheels 7031 are respectively fixedly connected to the outer sidewalls of any two adjacent threaded sleeves 701. One end of the worm 7032 is rotatably connected to the inner cavity sidewall of the bearing plate 601, and the sidewall of the worm 7032 meshes with the plurality of worm wheels 7031.

[0055] It should be noted that when the user rotates the worm gear 7032, the worm gear 7032 drives the multiple worm wheels 7031 meshing with it to rotate synchronously. The worm wheels 7031 drive the corresponding threaded sleeves 701 to rotate, thereby realizing the synchronous lifting and lowering adjustment of the multi-layer bearing plates 601. This provides a labor-saving and synchronous layer height adjustment mechanism, avoiding the imbalance caused by individual adjustment of each layer, and improving the convenience of operation and structural stability.

[0056] like Figure 3 As shown, a lower clamping plate 605 is fixedly connected to the top wall of the planting board 602, and an upper clamping plate 606 is detachably connected to the top of the lower clamping plate 605. An insertion hole 607 is provided between the upper clamping plate 606 and the lower clamping plate 605.

[0057] like Figure 6 as well as Figure 7 As shown, the nutrient solution circulation assembly 200 includes a main water tank 201, a circulating water pump 202, and a main supply pipe 203. The main water tank 201 is detachably connected to the bottom of the three-dimensional support 100. The circulating water pump 202 is detachably connected to the outer wall of the main water tank 201. The input end of the main supply pipe 203 is inserted into the inner cavity of the main water tank 201. Multiple branch pipes 204 are detachably connected to the side wall of the main supply pipe 203. The multiple branch pipes 204 pass through multiple insertion holes 607 respectively. Multiple drip irrigation pipes 205 are bolted to the side wall of the multiple branch pipes 204. Multiple irrigation holes 206 are opened at the bottom of the multiple drip irrigation pipes 205. The multiple irrigation holes 206 are located directly above the multiple planting holes 604.

[0058] It should be noted that the circulating water pump 202 pumps the nutrient solution in the main water tank 201 into the main supply pipe 203, and then distributes it to the drip irrigation pipes 205 of each layer through the branch pipe 204. The nutrient solution is precisely dripped into the root area of ​​the vegetables in each planting hole 604 through the irrigation hole 206 at the bottom of the drip irrigation pipe 205, so as to realize the active and uniform supply of nutrient solution, improve the accuracy of the nutrient solution supply in the root area, and promote the uniform growth of vegetables.

[0059] like Figure 6 as well as Figure 7 As shown, the nutrient solution circulation assembly 200 also includes a return pipe 207 and a recovery tank 208. The recovery tank 208 is detachably connected to the bottom of the three-dimensional support 100, and the recovery tank 208 is connected to the main water tank 201 through a conduit. The return pipe 207 is inserted through the side wall of the recovery tank 208, and multiple branch pipes 209 are inserted through the side wall of the return pipe 207. The multiple branch pipes 209 are respectively inserted under the multiple support plates 601.

[0060] It should be noted that the unabsorbed nutrient solution in the culture tank 603 flows into the branch pipe 209 through the recovery pipe 800 below the support plate 601, then collects in the return pipe 207, and finally flows back to the recovery tank 208. The nutrient solution in the recovery tank 208 then returns to the main water tank 201 through the conduit, forming a closed loop, realizing the recycling of nutrient solution, reducing nutrient solution waste, and increasing the dissolved oxygen content in the nutrient solution through circulation, preventing root rot due to lack of oxygen.

[0061] like Figure 6 as well as Figure 7 As shown, multiple support plates 601 are each inserted with a recovery tube 800 at their bottom ends. One end of each recovery tube 800 is inserted into the bottom end of multiple culture tanks 603, and the other end of each recovery tube 800 is inserted into the inner cavity of multiple branch tubes 209.

[0062] It should be noted that the residual nutrient solution at the bottom of each culture tank 603 flows into the branch pipe 209 through the recovery pipe 800 under the action of gravity and the control component 400, and is then uniformly recovered through the return pipe 207. This ensures that there is no excessive liquid accumulation in each culture tank 603, and is used to achieve independent drainage and centralized recovery of each culture tank 603, avoid cross-flow of nutrient solution between layers, and simplify the pipeline layout.

[0063] like Figure 8 As shown, the control component 400 includes a controller 401, a nutrient solution concentration sensor 402, and a liquid level sensor 403. The nutrient solution concentration sensor 402 is detachably connected to the inner wall of the main water tank 201, and the liquid level sensor 403 is detachably connected to the top wall of the inner cavity of the main water tank 201. The controller 401 is detachably connected to the outer wall of any of the support plates 601. The controller 401 is electrically connected to the nutrient solution concentration sensor 402 and the liquid level sensor 403 respectively.

[0064] It should be noted that the nutrient solution concentration sensor 402 monitors the nutrient solution concentration value in the main water tank 201 in real time, the liquid level sensor 403 monitors the liquid level height, the controller 401 receives and initiates sensor signals, and uses them to control the operation of the automatic liquid replacement component 300 at regular intervals. The controller compares the signal with a preset threshold to determine whether liquid replacement or replenishment is needed. This enables automatic monitoring of the nutrient solution status, provides a basis for automatic liquid replacement, avoids frequent manual inspections, and improves the level of intelligent management.

[0065] like Figure 6 as well as Figure 7 As shown, the automatic fluid replacement assembly 300 includes a drain solenoid valve 301 and a replenishment pump 302. The drain solenoid valve 301 is detachably connected to the bottom of the main water tank 201, and the replenishment pump 302 is detachably connected to the outer wall of the main water tank 201. The input end of the replenishment pump 302 is inserted into the external new nutrient solution storage tank, and the output end of the replenishment pump 302 is inserted into the main water tank 201.

[0066] It should be noted that when the controller 401 determines that the nutrient solution needs to be replaced (such as when the nutrient solution concentration exceeds the standard or the timed period is reached), it first opens the drain solenoid valve 301 to drain the old nutrient solution; after the liquid level sensor 403 detects a low liquid level, it closes the drain solenoid valve 301 and starts the replenishment pump 302 to draw fresh nutrient solution from the external new nutrient solution storage tank and inject it into the main water tank 201 until the liquid level reaches the set height, thereby realizing the automatic and periodic replacement of the nutrient solution, ensuring the long-term stability of the nutrient solution composition, greatly reducing the frequency of manual maintenance, and improving the uniformity of vegetable growth and survival rate.

[0067] In the specific implementation process, this technical solution can be further optimized and explained in the following aspects:

[0068] Regarding the adjustment accuracy and stability of the mounting component 700: Because the drive component 703 employs a meshing structure of worm 7032 and worm wheel 7031, the worm 7032 transmission has a self-locking characteristic. This means that when the user stops rotating the worm 7032, the worm wheel 7031 cannot reverse the rotation of the worm 7032, thus ensuring that the support plate 601 can be stably maintained in its adjusted position and will not automatically slide down due to gravity or vibration. This is particularly important in practical applications for culture layers 600 that bear significant weight. Simultaneously, the design of multiple worm wheels 7031 meshing with the same worm 7032 ensures the synchronous lifting and lowering of each support plate 601, avoiding the problem of inconsistent spacing between layers due to individual adjustments.

[0069] Working principle and usage process of this invention:

[0070] Working principle:

[0071] The controller 401 in the control component 400 starts the circulating water pump 202 according to a preset cycle, accurately dripping the nutrient solution in the main water tank 201 into the vegetable roots in each layer of the cultivation tank 603 through the main supply pipe 203 and the drip irrigation pipe 205. The unabsorbed nutrient solution returns to the main water tank 201 through the recovery pipe 800, the return pipe 207 and the recovery box 208, forming a cycle of oxygenation. At the same time, the nutrient solution concentration sensor 402 and the liquid level sensor 403 monitor the nutrient solution status in real time. When the nutrient solution concentration value exceeds the standard or the liquid replacement cycle is reached, the controller 401 automatically opens the drain solenoid valve 301 to discharge the old liquid, and then starts the replenishment pump 302 to inject new liquid from the external storage tank. The LED plant growth lights 500 at the bottom of each layer of the support plate 601 automatically supplement the light according to the set time. The user can adjust the layer height synchronously through the drive component 703 and use the upper and lower clamps 605 to fix the plant stems, thereby realizing the integrated intelligent operation of automatic nutrient solution circulation, automatic liquid replacement, light compensation and structural adjustment.

[0072] Usage process

[0073] Step 1: Assembly of the device and adjustment of the floor height

[0074] First, the user places the 3D support frame 100 in a suitable location on the balcony according to the balcony space dimensions and the types of vegetables planned to be planted. Then, by operating the worm gear 7032 in the drive assembly 703, the worm wheel 7031 and the threaded sleeve 701 are driven to rotate, adjusting the vertical spacing between the multiple support plates 601. For leafy vegetables, a smaller layer spacing is adjusted; for taller vegetables such as tomatoes and peppers, a larger layer spacing is adjusted. After adjustment, the self-locking characteristic of the threaded sleeve 701 and the threaded rod 702 keeps the layer height fixed.

[0075] Step Two: Planting Preparation

[0076] The user cleans the culture troughs 603 on each layer of the support plate 601, and then covers and fixes the planting plate 602 to the upper surface of the support plate 601. The vegetable seedlings, along with the sponge wrapping the roots, are placed into the planting basket, and then the planting basket is placed into the planting hole 604 on the planting plate 602, so that the roots extend into the space of the culture trough 603 through the planting hole 604.

[0077] Step 3: Nutrient solution injection and initial setup

[0078] The user injects the prepared nutrient solution into the main water tank 201 up to the highest water level detected by the level sensor 403. The user then sets the operating cycle of the circulating water pump 202 (e.g., working for 30 minutes and stopping for 30 minutes), the solution replacement cycle (e.g., 15 days), the nutrient solution concentration thresholds (e.g., lower limit 1.2 mS / cm, upper limit 3.0 mS / cm), and the daily operating time of the LED plant growth light 500 (e.g., 12 hours) on the controller 401. After setting, the controller 401 automatically starts operating.

[0079] Step 4: Artificially replenish new nutrient solution

[0080] Users only need to periodically check the liquid level in the external nutrient solution tank. When the fresh nutrient solution in the tank is about to run out, users can manually add prepared concentrated nutrient solution or nutrient solution diluted according to the ratio. Other than this, users do not need to perform any other daily operations.

[0081] Step 5: Vegetable Harvesting and Equipment Cleaning

[0082] When the vegetables reach harvestable size, the user opens the upper clamp 606 and removes the vegetables, along with the planting basket, from the planting hole 604. After harvesting, the user can remove the planting plate 602 from the support plate 601, clean and disinfect all components, and then replant the next batch of vegetable seedlings to begin the next planting cycle.
